Fluorescence Polarization

Fluorescence polarization measurements are made using an optical system that includes polarizing filters in the light path. Samples in the microplate are excited using polarized light, and depending on the mobility of the fluorescent molecules found in the wells, the light emitted will either be polarized or not.

Detection of circular polarization in light scattered from

May 12, 2009The identification of a universal biosignature that could be sensed remotely is critical to the prospects for success in the search for life elsewhere in the universe. A candidate universal biosignature is homochirality, which is likely to be a generic property of all biochemical life. Because of the optical activity of chiral molecules, it has been hypothesized that this unique characteristic Get price

DC Polarization

DC insulation resistance (IR) and polarization index (PI) testing is very widely used to assess the condition of the rotor and stator windings in motors and generators. The IR/PI tests are good at identifying contaminated windings; however, such issues as thermal deterioration or abrasion of the insulation due to coil vibration, are not detected by the IR/PI test in modern insulation.
